Need some help here. I've a Eagle Model/Racing Pocket Charger V.3 and have been using for the past 4 months. All the while no problem but now whenever I plug the battery for charging, it gives out the ERROR code. When I stop the charging, it returns to normal code. I've tried with different batteries and it's the same. Wonder what's wrong with it. Anybody have experience with this charger, please help. Thanks in advance.
